Abstract (en)
A load driving device (1) according to an aspect of the invention may includes an output transistor (T1) connected between a power supply line (PWR) and an output terminal (OUT), a load (11) connected between the output terminal (OUT) and a first ground line (GND1), a control circuit (13) connected between a gate of the output transistor (T1) and a second ground line (GND2), the control circuit (13) controlling turning on/off of the output transistor (T1), and a compensation transistor (14) that turns on when a potential of the second ground line (GND2) assumes a predetermined value or higher, thereby maintaining an off state of the output transistor.
